Self-supported Cu2S/Cu(OH)(2) composite nanorods were grown on Cu foam by hydrothermal treatment and showed high sensitivity and good anti-interference ability for non-enzymatic glucose sensing.
Self-supported Cu2S/Cu(OH)(2) composite nanorods for highly sensitive non-enzymatic glucose sensing were in situ grown on Cu foam by simple hydrothermal treatment of aligned Cu(OH)(2) nanorods. The physicochemical and electrochemical properties of the as-fabricated Cu2S/Cu(OH)(2) composite nanorods were characterized by scanning electron microscopy, transmission electron microscopy, x-ray diffraction, Raman spectroscope, x-ray photoelectron spectroscope, cyclic voltammetry, electrochemical impedance spectroscopy, amperometric i-t measurements. The mechanism of the composite nanorods produced on conductive substrates was also explored. The electrode exhibits a sensitivity of 9626.88 mu A mM(-1) cm(-2) towards glucose with good anti-interference ability, indicating it a promising electrode material for the enhanced non-enzymatic glucose detection.
